In the ethereal atmosphere of snows and mountains, where blue skies kiss verdant valleys, where sunrise and sunset and the sweet songs of the nightingales compose a vivid melody of youth and weave colourful patterns of beauty, the poetry of their first love unfolds.

Sonia and Sunil...their love was as lyrical as the flight of birds at dawn: as sweet as the pink blush of a rosebud: as lovely as light and as pure as the snows of the hills. Free from all doubts and suspicion, they stood on the threshold of faith and confidence, unmidful of tomorrow, singing the song of love. Sonia and Sunil were in search of a new name for their love for each other. On the strength of their love and confidence, defying all obstacles they got married.

Before the mehndi was even dry on Sonia's hands, before Sunil could settle down in the sustained peace of their happy marriage, something suddenly happened. The marital bliss was shattered one day when Dhiraj tried to molest Sonia and to save his wife's honour Sunil dealt a fatal blow to Dhiraj. Leaving his wife and son Rinku, Sunil went away, far away from Sonia leaving her helpless to fight against her own fate.

Sonia tossed by fate and time valiantly struggled for life. She found a friend in Chandni and her small daughter Pinky. Chandni shared Sonia's sorrow: Sonia shared Chandni's love.

One day Sonia met Sunil in Chandni's house-not as her husband and Rinku's father. Sonia was distressed, she could not believe her own eyes. But Sunil was standing in front of her with a new name and a new face.

How did it all happen? Why did it happen? Sunil, Sonia, Chandni had no answer to these questions.

Somewhere, hidden in the lives of each of these three fascinating people was a "daag" (stain).
